Keeping the Faith: A History of Northern Soul
The Northern Soul scene emerged in Britain during the late 1960s and 1970s and it is a cultural and music scene largely associated with the 1970s. Initially, American soul music arrived in Britain during the 1960s either through the work of leading African-American recording stars especially on the Motown or Stax label or as music made by lesser known artists which was sought after by collectors in Britain. From the late 1960s this was known as the ‘rare soul’ scene. These were recordings from artists who had been unsuccessful or had only made one or a couple of recordings or where on smaller and rarer US labels or where from mainstream soul artists, but were not commercially successful or were recorded before they had achieved fame. The soul underground’ was one of particular interest to the British ‘Mods’ (‘Modernist’) movement during the 1960s mainly in the major cities and especially in Londo
Supporting service discovery, querying and interaction in ubiquitous computing environments.
In this paper, we contend that ubiquitous computing environments will be highly heterogeneous, service rich domains. Moreover, future applications will consequently be required to interact with multiple, specialised service location and interaction protocols simultaneously. We argue that existing service discovery techniques do not provide sufficient support to address the challenges of building applications targeted to these emerging environments. This paper makes a number of contributions. Firstly, using a set of short ubiquitous computing scenarios we identify several key limitations of existing service discovery approaches that reduce their ability to support ubiquitous computing applications. Secondly, we present a detailed analysis of requirements for providing effective support in this domain. Thirdly, we provide the design of a simple extensible meta-service discovery architecture that uses database techniques to unify service discovery protocols and addresses several of our key requirements. Lastly, we examine the lessons learnt through the development of a prototype implementation of our architecture
Writing support for overseas students: quick fix or responsive solution?
The number of overseas finalists in both the School of Computing & Engineering and the Business School of Huddersfield University has increased markedly in recent years particularly from Europe and the new accession states of the EU. While the level of functional English of these students is acceptable, the academic traditions to which many are accustomed is not adequate preparation for studying in English, given that they are expected to complete a substantive final year dissertation.
A programme of writing skills support has been developed which helps the students adapt quickly to the demands of study. Support began four years ago with a pilot course and has now developed into a term-long series of workshops with the additional option of further one-to-one tutorial support. Student time on the final year is at a premium and the main challenge is to provide useful learning opportunities in a limited timescale while encouraging attendance. An important principle informing pedagogy is that students learn what is purposeful in terms of the desired outcomes applicable to their degree courses.
Quantitative research undertaken on levels of student attendance and achievement indicates that this approach has had a positive impact on student performance in the final year
Free products and continuous bundles of C*-algebras
The purpose of this thesis is to investigate the properties of free products of C*-algebras and continuous bundles of C*-algebras. We also consider how these two areas are connected.
In the first chapter we present background material relevant to the thesis. We discuss nuclearity, exactness and Hilbert C*-modules. Then we review the definitions and properties of bundles and free products of C*-algebras.
The second chapter considers reduced amalgamated free products of C*-algebras. We show that, if the initial conditional expectations involved are all faithful, then the resulting free product conditional expectation is also faithful.
In the third chapter we are interested in the properties of reduced free product C*-algebras. We introduce the orthounitary basis concept for unital C*-algebras with faithful traces and show that reduced free products of C*-algebras with orthounitary bases are, except in a few special cases, not nuclear. Building on this, we then determine the ideals in a certain tensor product C v Cop of the reduced free product with its opposite C*-algebra. In the second half of the chapter, we use Cuntz-Pimsner C*-algebras to study reduced free products of nuclear C*-algebras with respect to pure states. We show that, if the G.N.S. representations of the C*-algebras involved contain the compact operators, then the reduced free product C* -algebra is also nuclear.
Chapter four looks at the minimal tensor product operation on continuous bundles of C*-algebras. We construct, for any non-exact C*-algebra C, a continuous bundle A on the unit interval [0,1] such that A C is not continuous. This leads to a new characterisation of exactness for C*-algebras. These results are then extended to allow for any compact infinite metric space as the base space.
Finally, we introduce free product operations on bundles of C*-algebras in chapter five. Both full and reduced free product bundles are constructed. We show that taking the free product (full or reduced) of two continuous bundles gives another continuous bundle, at least when the bundle C*-algebras are exact

Voltage-gated sodium channels (NaV) in GtoPdb v.2021.3
Sodium channels are voltage-gated sodium-selective ion channels present in the membrane of most excitable cells. Sodium channels comprise of one pore-forming α subunit, which may be associated with either one or two β subunits [177]. α-Subunits consist of four homologous domains (I-IV), each containing six transmembrane segments (S1-S6) and a pore-forming loop. The positively charged fourth transmembrane segment (S4) acts as a voltage sensor and is involved in channel gating. The crystal structure of the bacterial NavAb channel has revealed a number of novel structural features compared to earlier potassium channel structures including a short selectivity filter with ion selectivity determined by interactions with glutamate side chains [274]. Interestingly, the pore region is penetrated by fatty acyl chains that extend into the central cavity which may allow the entry of small, hydrophobic pore-blocking drugs [274]. Auxiliary β1, β2, β3 and β4 subunits consist of a large extracellular N-terminal domain, a single transmembrane segment and a shorter cytoplasmic domain.The nomenclature for sodium channels was proposed by Goldin et al., (2000) [144] and approved by the NC-IUPHAR Subcommittee on sodium channels (Catterall et al., 2005, [52])

Retention of computing students in a London-based university during the Covid-19 pandemic using learned optimism as a lens: a statistical analysis in R
The aim of this research project is to investigate the low retention rate among the foundation and first year undergraduate students from the School of Computing and Digital Media in a London based university. Specifically, the research is conducted during the Covid-19 pandemic using learned optimism as a lens. The research will aid the university to improve retention rate as the overall dropout has been increasing in the last few years. The current study employed an exploratory investigation approach by using statistical modelling analysis in R to predict behavioural patterns. The quantitative data analysis conducted aims to support the efforts of the School of Computing and Digital Media of a London based university to re-evaluate its retention strategies in foundation and first year computing students. The main outcomes of the analysis is that students with a foreign qualification are optimistic, while students with other or not known qualification are mildly pessimistic. In addition, students with a BTECH, Higher Education diploma or A level qualification are generally more pessimistic especially if they are also black ethnicity, or are also not black ethnicity, aged under 34 and British
